In this paper an isolated wind-diesel hybrid power\r\nsystem has been considered for reactive power control study having\r\nan induction generator for wind power conversion and synchronous\r\nalternator with automatic voltage regulator (AVR) for diesel unit is\r\npresented. The dynamic voltage stability evaluation is dependent on\r\nsmall signal analysis considering a Static VAR Compensator (SVC)\r\nand IEEE type -I excitation system. It's shown that the variable\r\nreactive power source like SVC is crucial to meet the varying\r\ndemand of reactive power by induction generator and load and to\r\nacquire an excellent voltage regulation of the system with minimum\r\nfluctuations. Integral square error (ISE) criterion can be used to\r\nevaluate the optimum setting of gain parameters. Finally the dynamic\r\nresponses of the power systems considered with optimum gain setting\r\nwill also be presented.\r\n",
